Input: pixcir_i2c_ts - move platform data
Let's move driver's platform data definitions from include/linux/input/ into include/linux/platform_data/ so that it stays with the rest of platform data definitions. Acked-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
